Trader consensus on Polymarket assigns a 100% implied probability to a 21°C high temperature in Shanghai today, backed by real-time observations from the official Xujiahui observatory peaking at 21°C around midday, precisely matching the China Meteorological Administration's (CMA) forecast issued late March 27. Mild southerly winds under 12 km/h advected warmer maritime air amid partly cloudy skies, aligning with ECMWF and GFS ensemble consensus for a 19–21°C maximum amid typical late-March variability (historical averages ~14–16°C). This skin-in-the-game positioning leaves scant room for alternatives. A realistic challenge would require prolonged cloud breaks for enhanced solar heating late afternoon, though declining solar angles and persistent overcast make this improbable; final CMA daily high report expected soon after sunset.
